Managing Collections

As with any data source, the maintenance requirements of a Verity collection are
dictated by the number, frequency, and type of changes that occur in the records.
You can run maintenance routines directly from either the
tags or via the Administrator Verity Collections page. For more information on this
topic, see the Knowledge Base article "Maintaining Collections" (ID# 1080) at http://
www.coldfusion.com/Support/KnowledgeBase/SearchForm.cfm.
The easiest way to perform collection management tasks is to create a ColdFusion
page that runs the operations, and then add the task on the Administrator Scheduler
page. The page presents a wide range of scheduling options.

Maintenance options

Choose an option based on the following function descriptions:

Securing a collection

Scenarios for restricting access to a Verity collection include:
Repair Runs internal Verity routines to fix corrupted records. If you suspect a
collection is corrupted, it is probably safest to repopulate it.
Optimize Packs the indexed data for better performance. You can use this
procedure, which is similar to database optimization, as part of routine
maintenance.
You should not use the
legacy code. The

Your Verity Collection" (ID# 416) at http://www.coldfusion.com/Support/

remove these items.
Delete on the Administrator Verity Collections page or in
the entire collection.
Update Repopulates the collection with changed records and new records and
adds a key if one is not part of the collection. This operation does not delete
records that have been deleted from the data source. To update a collection from
the Administrator Verity main page, select a collection on the list, click Index, and
then click Update on the index page.
